If this is a Lone Star pattern, you might want to check Eleanor Burns website Quilt in a Day to see what helpful hints she has. I remember that you should always keep the bias side of the diamonds on the bottom. I also recommend to do basting first then check that everything lines up before sewing a normal stitch length. This pattern requires a lot of patient. LOVE your colors. I would love to see a picture of which side you decide to be the center!! GOOD LUCK !!!
